Abstract: PROBLEM TO BE SOLVED: To make it possible to hold the elasticity of an elastic body and maintain the vibration damping performance of the elastic body with a simple configuration by keeping the elastic body at a fixed temperature or higher without providing a heat source for heating the elastic body. SOLUTION: By setting an exhaust part for heat from a fixing roller 5 to pass the periphery of a vibration-proof rubber 13 and a damping sheet 14, the rubber 13 and the sheet 14 are warmed by the exhaust heat from the roller 5. Thus, the rubber 13 and the heat sheet 14 are kept at the fixed temperature or more without providing the heat source for heating the rubber 13 and the sheet 14. Therefore, the vibration-proof action of the rubber 13 and the sheet 14 is not lowered.

Further, to the variable capacitor 16, the applied voltage before the power failure held at the voltage storage circuit 32 added with the voltage cancelling the changing part of oscillation frequency corresponding to the difference of the storage temperature of crystal are fed. Thus, the power supply at power failure can be smaller and the error in the oscillation frequency is very small.

Filed: 1985-01-28
Abstract: PURPOSE:To prevent the speed change shock generated in the slip control for a lock-up clutch by supplying the bypass flow through a flow-rate control valve in which the throttle degree varies according to the throttle pressure into a passage connecting a lock-up control valve and a lock-up control chamber.
